TUM BLING-Box.

SPECIFICATION forming part of Letters Patent No. 691,802, dated January248, 1902. Y

Application filed July 13, 1901. Serial No. 68,230. (No model.)

To all whom it may con/cern.:

Be it known that I, WILLIAM F. PATTON, a citizen of theUnitedStates,'residin g at Toledo, in the county of Lucas and State of Ohio,have invented new and useful Improvements in Tumbling-Boxes, of whichthe following is al The object of the invention is to provide a deviceof this character in which therubbin g action is facilitated by givingthe castings and conned rubbing material a rotary tumbling as well as asliding motion, thus causing the castings to simultaneously move in twodifferent paths and effectually bringing their surfaces into contactwith each othery and with the rubbing material; and a further object ofthe invention is to provide a device adapted for other uses, such asfor` imparting rotary motion to molds vfor making 'hollowseamlessbodies, as set forth in my applica-4 tion filed of even dateherewith for Process of making hollow bodies, Serial No. 68,690. Withthese and otherobjeots in vView the invention consists of certain novelfeatures of construction, combination, and arrangement of parts, as willbe hereinafter more fully described, and particularly pointed 'out inthe appended claims.

In the accompanying drawings, Figure lis a' perspective view of atumbling-box constructed in accordance with my invention. Fig. 2 is atop plan view of the same; and Fig. 3 is a fragmentary detailperspective view of the box-sections, showing the same at their pointsof connection.

Referring now y more particularly to the drawings, the numeral ldesignates the box, which comprises in its construction twocorrespondingcomparatively long and narrow boxes or chambers 2 and 3, which arecrossed to form a substantially X-shaped rotating box or frame. Thesebox-sections 2 and 3 are connected at their ends by straps or brackets 4to sprocket-wheels 5, journaled to rotate upon the supporting-standards6 and having applied thereto sprocket-chains 7, whereby wheels from anysuitable source of power. Each box section or compartment is providedwith a removable cover 8, held closed at its ends by suitablekeeper-pins or cross-bolts 9 and at the center bya hasp or othersuitable fastening device 10. The hasp lO, which closes the cover ofeach section, is preferably hinged to the other section, so that the twohasps when connected to close the covers will also serve to connect thetwo boxes or compartments 2 and 3 at their point of crossing and toreinforce them at said point.

In operation the covers 8 are removed and the castings, together withbroken particles of iron, filings, or other friction or rubbingmaterial, placed inside'the boxes or compartments 2 and 3 of thetumbling device, the covers 8 then closed and fastened, and rotarymotion communicated to the tu mbling device. As the box or tumblingdevice 1 revolves it will be seen that it will not only communicate atumbling action to the castings by its circular path of movement, butthat thesections or compartments l2 and 3 lwill form inclined planes,down which the castings and conlined rubbing material wll'slide from oneVend of each box to the other, and that a continuous back-and-forthsliding motion of the castings and rubbing material will thus be setup.- causingV all the surfaces of the castings to be exposed andlto bebrought into contact with each other and with the rubbing material,whereby the operation of smoothing or finishing the surfaces of thecastings and reducing all roughness and irregularities will be speedilyand elfectually performed.

The device is also adapted for a number of other uses and may be, as setforth in myV other pending application hereinbefore referred to,employed for imparting rotary morotary motion may-be communicated to thetionv to molds for making hollow seamless bodies. Hence I do not limitthe invention for use in removing the irregularities of surfaces fromcastings, but reserve the right to employ it for any purpose for whichit is now or may hereafter be found adaptable.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

l. In a tumbling-box, the combination of a box composed of sectionscrossed to form an IOS to said sprocket-wheels, substantially asdescribed.

2. In a tumbling-box, the combination of sprocket-wheels, means forcommunicating motion thereto, a tumbling-box composed of sectionscrossed to form a rotating box-frame, brackets connecting the ends ofsaid sections to the sprocket-wheels, removable covers for i thebox-sections, and means for holding said covers closed and connectingthe box-sections to each other, substantially as described.

In testimony whereof I have hereunto set I5 my hand in the presence oftwo subscribing witnesses.

VILLIAM F. PATTON.
